Description

FIELD OF THE INVENTION

The present invention relates generally to data processing. More specifically, the present invention is methods and systems for facilitating locating an individual based on UHF RFID (Ultra High-Frequency Radio Frequency Identification) tags.

BACKGROUND OF THE INVENTION

The field of data processing is technologically important to several industries, business organizations, and/or individuals. In particular, the use of data processing is prevalent for facilitating locating an individual.

For all parents or caregivers, one of the concerns is always what if they don't find their kid. One obvious answer is to give them a GPS device, such as a GPS watch. But what about indoor places, or big shopping malls with multilevel stores. In big shopping malls when a kid is reported lost, the parents or caregivers start looking at the security cameras and try to find the kid and if they don't find the kid after a certain number of minutes, the parent may lock the doors to make sure the kid does not go out, which might be too late.

Existing techniques for facilitating locating an individual are deficient with regard to several aspects. For instance, current technologies do not locate the kid in indoor places. Currently for indoors like amusement parks, big shopping malls, the only way to locate a lost kid or pet is to go through the security cameras which is not accurate and most of the time it is too late as if a kid has left the building it cannot be located and by the time reviewing the recordings, the kid or pet might have gone too far.

Therefore, there is a need for improved methods and systems for facilitating locating an individual based on UHF RFID tags that may overcome one or more of the above-mentioned problems and/or limitations.

Overview

The present disclosure describes methods and systems for facilitating locating an individual based on UHF RFID tags. Further, for all parents or caregivers, one of the concerns is always what if they don't find their kid. One obvious answer is to give them a GPS device, such as a GPS watch. But what about indoor places, or big shopping malls with multilevel stores. In big shopping malls when a kid is reported lost, the parents or caregivers start looking at the security cameras and try to find the kid and if they don't find the kid after a certain number of minutes, the parent or security team may lock the doors to make sure the kid does not go out, which might be too late.

Further, the disclosed system may be configured for using a UHF RFID (Ultra High-Frequency Radio Frequency Identification) tag attached to the kid that may be used to easily locate the kid in indoor places. Currently for indoors like amusement parks, big shopping malls, the only way to locate a lost kid or pet is to go through the security cameras which is not accurate and most of the time it is too late as after a kid has left the building, the kid cannot be located, and by the time reviewing the recordings, kid or pet might have gone too far.

Further, the disclosed system may be associated with a passive UHF RFID tag attached to the Kid, by either having it as a sticker or a wristband or necklace, or any other form that is being attached to the kid. For example embedded in the uniform. Further, the disclosed system may include RFID readers in the entrances, exits, or places where usually people gathered. Further, it may be easy to locate a kid in a matter of minutes by checking the last known location.

Further, the disclosed system may be configured for locating, kids, pets in indoor locations such as a shopping mall, large places like aquariums, playgrounds, etc. Further, the disclosed system may be configured for tracking people and their interests in a shopping center or a museum. Further, disclosed system may be configured for activating an alarm by notifying a lost kid as soon as it is detected close to any of the readers. Further, disclosed system may be configured to count people inside and update the total number in real-time as people leave the place.

Further, the UHF RFID tags may be read by a proper antenna from a distance even more than 2 meters. The UHF RFID reader (or the reader) may be configured to read multiple tags at the same time and also distinguish the distance between the tag (RFID tag) and the antenna. By installing the antenna at a proper angle, the disclosed system may identify the direction of movement where the person is moving (entering or existing). As soon as the tag is read by the reader (or the UHF RFID reader), a tag UID (Unique Identification Number) along with a reader ID may be sent to a server. The server reads the tag and sends a location update to a person who has registered the tag. Further, if a tag is marked as lost, the reader may start the alarm as soon as the lost tag is read by the reader.

Further, normal conventional RFID tags have a very short reading distance and require tags to be very close to the reader. But using the UHF RFID tags makes it doable to read tags from distance.

Since the antenna face may be pointing at one side of a gate (wherein the gate can be installed on a door or a wall of a room and the antenna can be configured to detect someone's movement entering the room), the reader detects a tag signal power and we can detect the direction of movement when someone enters or leaves a gate. As the tag gets close to the antenna from the front, the antenna starts reading and the signal power. It starts from low and goes to high. Further, when the tag enters behind the antenna, the signal may not be detected until the tag passes the gate. In this case, it starts with a high signal and goes low, as the tag passes by. This can help detecting if the tag holder has entered or left the building or a place.

Further, the disclosed system may include an indoor positioning system that includes three main components, namely, the readers, simultaneous multi-tag RFID reader with an antenna, and the UHF RFID tag. Further, the UHF RFID tags may be distributed in a form or sticker, embedded into a uniform or wristband or necklace, or even attached to a bag or cart. Further, the disclosed system may be associated with an application server that receives data from the reader and distributes it to mobile or other devices.

By way of non-limiting example, the online platform 100 for facilitating locating an individual based on UHF RFID tags may be hosted on a centralized server 102, such as, for example, a cloud computing service. The centralized server 102 may communicate with other network entities, such as, for example, a mobile device 106 (such as a smartphone, a laptop, a tablet computer, etc.), other electronic devices 110 (such as desktop computers, server computers, etc.), databases 114, and sensors 116 over a communication network 104, such as, but not limited to, the Internet. Further, users of the online platform 100 may include relevant parties such as, but not limited to, end-users, service providers, care providers, and administrators. Accordingly, in some instances, electronic devices operated by the one or more relevant parties may be in communication with the online platform 100.

A user 112, such as the one or more relevant parties, may access the online platform 100 through a web-based software application or browser.
